How to Install Kernel 4.16 in Ubuntu / Linux Mint

Last updated: April 2, 2018

Linux Kernel 4.16 was released yesterday. Linus Torvalds announced in lkml.org:

So the take from final week of the 4.16 release looks a lot like rc7, in that about half of it is networking. If it wasn’t for that, it would all be very small and calm.

We had a number of fixes and cleanups elsewhere, but none of it made me go “uhhuh, better let this soak for another week”. And davem didn’t think the networking was a reason to delay the release, so I’m not.

End result: 4.16 is out, and the merge window for 4.17 is open and I’ll start doing pull requests tomorrow.

Outside of networking, most of the last week was various arch fixlets (powerpc, arm, x86, arm64), some driver fixes (mainly scsi and rdma) and misc other noise (documentation, vm, perf).

The appended shortlog gives an overview of the details (again, this is only the small stuff in the last week, if you want the full 4.16 changelog you’d better get the git tree and filter by your area of interest).

Linux Kernel 4.16 release highlights:

  • Spectre / Meltdown mitigation & other security updates.
  • L2 CDP support for L2 cache partitioning on Intel CPUs
  • Correct AMD Zen temperature reporting for the Ryzen Threadripper 1900X processor.
  • P-State driver support for Skylake X servers.
  • POWER memory protection keys support
  • Oracle DAX driver for SPARC co-processor
  • Jailhouse guest support for non-root users

How to Install Kernel 4.16 in Ubuntu:

Other than using a graphical tool UKUU to install the latest mainline kernel packages, following steps will tell you how to manually download and install it in all current Ubuntu releases.

The mainline kernel PPA has made the new kernel binaries for Ubuntu, available for download at the link below:

Depends on your OS type, download and install the packages in turns:

  1. linux-headers-4.16.0-xxxxxx_all.deb
  2. linux-headers-4.16.0-xxx-generic(/lowlatency)_xxx_amd64(/i386).deb
  3. linux-image-4.16.0-xxx-generic(/lowlatency)_xxx_amd64(/i386).deb

Select generic for common system, and lowlatency for a low latency system (e.g. for recording audio), amd64 for 64bit system, i386 for 32bit system, or armhf, arm64, etc for other OS types.

To get the Kernel 4.16 from the command console, run the commands below one by one:

For 64-bit OS:

cd /tmp/

wget -c http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.16/linux-headers-4.16.0-041600_4.16.0-041600.201804012230_all.deb

wget -c http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.16/linux-headers-4.16.0-041600-generic_4.16.0-041600.201804012230_amd64.deb

wget -c http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.16/linux-image-4.16.0-041600-generic_4.16.0-041600.201804012230_amd64.deb

sudo dpkg -i *.deb

for 32-bit OS:

cd /tmp/

wget -c http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.16/linux-headers-4.16.0-041600_4.16.0-041600.201804012230_all.deb

wget -c http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.16/linux-headers-4.16.0-041600-generic_4.16.0-041600.201804012230_i386.deb

wget -c http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.16/linux-image-4.16.0-041600-generic_4.16.0-041600.201804012230_amd64.deb
sudo dpkg -i *.deb

After installed these .debs, restart and enjoy!

Uninstall Linux Kernel 4.16:

Start/restart your machine and select boot with the previous kernel in Grub2 -> Advanced menu. Then use Ubuntu Tweak, or other system tool to remove the Kernel 4.16, or you may see this how to remove old kernels tutorial.

Last updated: September 11, 2019

Open source Raw image processor RawTherapee 5.4 was released a few days ago. Here’s how to install it in Ubuntu 16.04, Ubuntu 17.10, Ubuntu 18.04, and derivatives.

New features in RawTherapee 5.4 include:

  • New default processing profiles, now the default look for raw photos closely matches the out-of-camera look with regard to tones and includes lens distortion and vignetting correction.
  • New histogram matching tool, to have RawTherapee automatically adjust the image for you to match the out-of-camera look with a single click of a button.
  • New HDR Tone Mapping tool to compress the light in scenes with a high dynamic range, allowing you to show details in both shadows and highlights in a realistic way.
  • New Local Contrast tool to boost clarity using a simple interface.
  • New color toning method L*a*b* Color Correction Grid.
  • New RCD demosaicing algorithm to minimize artifacts even with artificial lighting and strong chromatic aberration.
  • New thumbnail overlay icons in the File Browser and Filmstrip to help you distinguish normal images from HDR and Pixel Shift ones.
  • Added support for showing out-of-gamut areas based on the output profile.
  • Added support for reading and writing metadata and ICC profiles to and from PNG images.
  • Added support for processing Sony Pixel Shift ARQ raw files – make sure that the ARQ extension is enabled in Preferences > File Browser > Parsed Extensions.
  • Create Sony ARQ raw files using https://github.com/agriggio/make_arq
  • Added support for saving 32-bit floating-point TIFFs clamped to [0;1].
  • Added profiled chromatic aberration correction support using Lensfun.
  • More tools now have an on/off switch.
  • The user interface is cleaner, with all power-house tools moved into a new “Advanced” tab to prevent slider-shock to newcomers.
  • The Metadata tab now lets you choose whether you want to copy metadata unchanged, edit metadata or strip metadata when saving images. Now you can also make metadata changes in batch mode.
  • The choice of whether the main histogram should display information using the working profile or the output profile is now available from the Editor tab’s top toolbar.
  • The Crop tool’s aspect ratio now defaults to that of the image, and RawTherapee automatically zooms-to-fit the crop once it’s placed.
  • RGB input-type ICC profiles can now be used as output profiles.
  • The saved reference image for profiling (created from within the Color Management tool) now contains metadata.
  • PNG and compressed TIFF images make use of better compression.
  • Shortcut key changes: Zoom-to-fit the crop using “f”, fit the whole image using “Alt+f”.

How to Install RawTherapee 5.4 in Ubuntu:

For Ubuntu 16.04, Ubuntu 17.10, Ubuntu 18.04, and derivatives, the new release is available via this PPA repository.

1. Open terminal either via Ctrl+Alt+T or by searching for “Terminal” from app launcher. When it opens, run command:

sudo add-apt-repository ppa:dhor/myway

Input your password (no visual feedback when typing) when it prompts and hit Enter to add the PPA.

2. After that, upgrade the software via Software Updater if a previous version was installed:

The upgrading process may be kept back if you were installing it from Ubuntu Software App.

A workaround is simply running following commands instead to install or upgrade RawTherapee:

sudo apt-get update

How to Remove:

To uninstall the free raw developer, run command in terminal:

sudo apt-get remove --autoremove rawtherapee
